Choosing the Right Plant Growth Regulators to Increase Yields and Income

In agricultural production, choosing the right plant growth regulators is one of the important means to increase yields and income. Below are some common and effective regulators and their main functions.

Main Plant Growth Regulators and Their Yield-Increasing Mechanisms
Plant growth regulators are diverse, with different regulators having different mechanisms of action and applicable scenarios. The following are several regulators widely used for increasing yields and income:


1. Brassinolide (BRs)

Core Function: Known as the "green hormone," it can comprehensively coordinate crop growth and development. It can enhance photosynthesis, improve crop resistance to stress (such as cold resistance, drought resistance, and disease resistance), promote cell division and elongation, thereby effectively promoting root growth, protecting flowers and fruits, promoting fruit enlargement, and improving quality.

Applicable Scenarios: Suitable for a variety of crops, especially effective in preventing low-temperature freezing damage, transplanting seedling establishment, and improving the quality and yield of fruits and vegetables.

2. Diethyl aminoethyl hexanoate (DA-6)

Core Function: Increases the content of chlorophyll, protein, and nucleic acids, enhancing the plant's efficiency in absorbing and utilizing water and fertilizer, thereby improving stress resistance (drought resistance, cold resistance) and promoting growth. Its characteristics include high activity and long-lasting effect, maintaining good efficacy even under low-temperature conditions.

Applicable Scenarios: Can be used year-round, with significant advantages in the low-temperature environments of autumn and winter. Suitable for various crops such as corn, tomatoes, and cabbage.


3. Sodium Nitrophenolates (Atonik)

Core Function: It has a bidirectional regulatory effect, promoting growth without causing excessive vegetative growth. It coordinates the balance between vegetative and reproductive growth, achieving increased yield and improved quality.

Application Scenarios: Can be used for foliar spraying, root treatment, etc., helping crops achieve stable growth and increased yield.

4. Gibberellic Acid (GA3)

Core Function: Primarily promotes cell elongation and division, significantly improving yield and quality. Commonly used to break seed dormancy, promote germination, and fruit setting.


5. Forchlorfenuron (CPPU / KT-30)

Core Function: Strongly promotes cell division and expansion, protecting flowers and fruits, increasing fruit setting rate, and promoting fruit enlargement. Widely used in crops such as tomatoes, cucumbers, and watermelons.
